Methods, apparatus, and computer-readable media are described herein related to a user interface (UI) that can be implemented on a head-mountable device (HMD). The UI can include a voice-navigable UI. The voice-navigable UI can include a voice navigable menu that includes one or more menu items comprising an original menu item and an added command menu item. The original menu item can be associated with one or more original commands, and the added menu item can be associated with one or more added commands, including a first added command. The interface can also present a first visible menu that includes at least a portion of the voice navigable menu. Responsive to a first utterance comprising the first added command, the interface can invoke the first added command. In some embodiments, the interface can display a second visible menu, wherein the first added command can be displayed above other menu items.
